Farmer-developed vegetable intercropping systems in southern Hebei, China
Autor: Qing Chen, Til Feike, Simone Graeff-Hönninger, Judit Pfenning, Wilhelm Claupein
Publikováno v: Renewable Agriculture and Food Systems. 25:272-280
The expansion of intensive vegetable production systems exacerbates ongoing resource degradation in China's Hebei province. There is an urgent need to develop and disseminate more sustainable vegetable production systems. Intercropping, the simultane
